+On macOS, [Homebrew](https://brew.sh) is used in order to install

-On OS X, autotools are distributed with [Mono.framework][osx-mono].

+When e.g. the `$(AndroidSupportedHostJitAbis)` MSBuild property contains
+`mxe-Win64` or `mxe-Win32`, the [M cross environment (MXE)](http://mxe.cc)
+will be built via [`external/mxe`](external/mxe). The MXE build in turn
+requires that `autopoint` be located within `$PATH`.
+
+Homebrew 1.2 and later do not install `autopoint` into `$PATH` when the
+`gettext` package is installed, which means that MXE can't be built.
+To fix this error, force-link the `gettext` package:
+
+	brew link --force gettext

+This will place `autopoint` into `$PATH`, allowing MXE to be built.
